How would you change Sony's Xperia Ion?

While Sony undergoes its transformation under Kaz Hirai, there's a suspicion that many of its divisions have just been treading water. Take the Xperia Ion, for instance. The company's AT&T LTE flagship shipped in June, yet still carried the dead weight of Gingerbread as the albatross around its neck. Sony's engineering prowess produced sleek hardware, a cracking display, good camera and it was priced at $99 -- but was that a draw with a two-year-old operating system and 2011-era internals? Probably not. But if you were in the minority who bought one of these, what do you think? If you were sure Sony's engineering gurus were reading your every word, what would you tell them to do differently next time?
